What's the difference?
GWM’s Tank 300 struck a chord with Australian buyers when it launched in 2023. The rugged, boxy design, serious off-roading ability and unbeatable value for money - especially compared with similar models like the Jeep Wrangler - won it a number of new fans.
But something was missing. With an uninspiring petrol engine and a patchy hybrid powertrain the only options, the Tank 300 was sorely missing a diesel.
GWM itself says about 75 per cent of models in the off-road-focused large and upper-large SUV segments are made up of diesel-powered SUVs, so it was missing out on a chunk of sales.
Thanks to some serious nudging from GWM Australia and New Zealand, the Chinese parent company saw the potential and have added a diesel engine to the mix. This is the same diesel unit found in the GWM Cannon and Cannon Alpha utes.
Is the diesel now the pick of the Tank 300 range? Or should you look at another oil-burning 4x4?
MG’s latest electric vehicle has arrived in Australia. The MG S5 EV replaces the super popular MG ZS EV. But don’t think of the MG S5 EV as just a replacement because if first impressions ring true this small budget electric SUV could be the new benchmark for the class.
The arrival could not be better timed. A multitude of new Chinese brands have been landing in Australia with small affordable electric SUVs such as the BYD Atto 3, Chery Omoda E5 and Zeekr X, while the MG ZS EV was getting older and uncompetitive even if its price was almost unbeatable.
Now the S5 EV has landed and our first impressions show it to be outstanding. We’ve tested it and can tell you how well it stacks up against the ZS EV and after you read this review you'll also know how well it may compare to its small budget electric SUV rivals.
The diesel is now the pick of the Tank 300 range. It’s the best fit for this vehicle and offers greater driver engagement than the petrol or hybrid.
It also has genuine off-road chops while still managing to suit family life.
While it could benefit from further refinements to on-road behaviour, cabin noise and the ADAS systems, none of these are deal breakers.
The fact that it is priced so keenly against some excellent competitors and is stacked with standard gear adds to the Tank 300’s appeal.
Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.
Benchmark is a big word. But I’ve been testing cars long enough to know when and where to use it, and if my motoring instincts are correct the MG S5 EV could be the new benchmark for budget small electric SUVs.
Still we’ve only driven one grade - the Essence with the bigger 62kWh battery. We need to get the other grades into the garage to test them too, but on first impressions the MG S5 is outstanding for price, practicality, styling, ownership, and the way it drives.
The only visible difference between the diesel and the petrol or hybrid 300s is a 2.4T badge. So you get the same boxy exterior as before.
It’s somewhat derivative and gives more than a nod to Jeep, but the design has intent - it looks capable off-road and for most people that’s enough. Luckily it is capable off-road. More on that later.
Inside the upright, shelf-like dash is appealing. I like that everything is nicely integrated, like the dual 12.3-inch screens which flow nicely into one another.
The big T-shaped three-spoke steering wheel looks cool and the aeronautical air vents are clearly inspired by Mercedes-Benz.
The chunky metal-look plastic glove box cover adds extra visual flair and the stitching throughout elevates the cabin further.
However, the futuristic looking gear shifter is chunky, takes up too much space and is unnecessary.
The MG S5 EV is a completely new car. Unlike the ZS EV which was a combustion car that was later turned into an EV, the S5 EV was designed from the start and built as an electric vehicle and that’s super important for everything from space to how it drives.
The S5 EV is a bigger car than the ZS EV. It’s 153mm longer and 40mm wider and it shares the same underpinnings as the excellent MG4 hatch.
The S5 EV looks a bit like the MG4 but an SUV version and I think the styling is a massive improvement over the ZS EV. This thing looks snatched with its sleeker shape and a smooth modern face, the blade-like LED running lights sitting atop the headlights and I really like the treatment to the tail-lights as well and the way the boot lid flicks up into a little integrated spoiler.
It's a far more refined, mature and prestigious look to the ZS EV. And while we're being completely subjective here I also think it's better looking and more refined than the BYD Atto 3 and Chery E5.
That same refinement and modernity is everywhere in the superb cabin from the clean dash design and door trims, to the steering wheel and floating centre console.
Up front the Tank 300 offers a commanding view of the road and it’s easy to find your perfect driving position thanks to the power-adjustable seats.
Those seats have good side bolstering but could do with a little extra cushioning for the thighs. The Nappa leather-appointed seats in the Ultra look and feel lovely.
Storage is average for the segment with room for larger bottles and additional flat items in the door pockets, and a well-sized central bin that also houses two cupholders, although they sit low in the cavity and two coffees sit awkwardly together.
The Tank has one USB-C port for charging only but another USB-A port up front for connectivity. You shouldn’t need that given Apple CarPlay and Android Auto is wireless.
Keen off-roaders will have fun with the extensive Tank Expert Mode in the multimedia screen, which allows you to individualise your 4WD experience.
Beyond that the screen is neatly laid out, responsive and easy to use. GWM has come a long way when it comes to in-car tech. The icons on the digital instrument cluster, however, are still too small.
There’s ample leg room in the rear, with space between my knees (I am 184cm tall) and the rear of the front seat, and enough toe room. It doesn’t feel enormously spacious across the rear row but three kids should be comfy. Headroom is enhanced by a scalloped section of the roof specifically for rear-seat passengers, but it doesn’t leave a huge amount of space for taller people.
The rear seat bench is flat but the backrests have some support and overall the seats back there are comfortable.
You’ll find lower rear-seat air vents, map pockets, a fold-down central arm rest with two cupholders, room for small bottles in the doors and two USB-A ports.
The boot can take 400 litres with all seats up and 1635L with the rear seats folded. That figure is measured from the floor to the top of the rear seats.
Jeep says the Wrangler has 898L capacity with all seats in place but that is measured from the floor to the roofline.
There is no under-floor storage in the 300’s boot and the full-size spare wheel is housed in traditional 4x4 fashion on the tailgate.
The MG S5 EV’s practicality is also outstanding and while it’s early days, it could be the new benchmark for the class. It's a spacious cabin with superb ergonomics and excellent storage.
Even as a taller person (I’m 189cm) there was plenty of elbow, shoulder and legroom for me as a driver and also to sit behind my driving position in the second row.
Storage is excellent with giant bottle holders in all the doors, stowage under the floating centre console, four cupholders and a flat space for your phone which also is a wireless charger on the Essence.
It’s such an ergonomic and practical cabin even the buttons are practical. There’s a volume dial, and physical buttons and switches for the climate control switch, not screen buttons.
And then there’s the boot, at 453 litres it’s about 10 litres bigger than the ZS EV’s cargo capacity. It's also 10L larger than the Atto 3 and a lot bigger than the Chery E5’s boot.
One of the key selling points across GWM’s entire range is value for money, and the Tank 300 has always had that in spades.
As with the petrol and hybrid 300, the diesel is offered in two well-specified model grades - Lux and Ultra.
At $47,990 drive-away, the Lux diesel is $2000 more than the Lux petrol, but $3000 cheaper than the Lux hybrid.
The Ultra diesel, at $51,990, is $1000 pricier than the petrol equivalent and $5000 more affordable than the hybrid Ultra.
The GWM Tank 300 diesel Lux is also more affordable than equivalent grades of a number of ladder-frame 4x4 SUV rivals like the Isuzu MU-X, Toyota Fortuner, SsangYong Rexton and the Ford Everest.
It’s also significantly more affordable than the Jeep Wrangler, with the Tank 300 Lux costing about $30,000 less than a Wrangler Unlimited Sport S.
Note however that many of those models - except the Wrangler - have the option of seven seats, whereas the Tank is strictly a five-seat proposition. If you want a third row, check out GWM’s Tank 500.
There are cheaper off-road large SUVs out there – the LDV D90 and Mahindra Scorpio. But the Tank 300 is a more refined and higher-quality offering than those models.
Standard gear in the Lux includes 17-inch alloy wheels, synthetic leather seats and steering wheel, power-adjustable front seats, dual-zone climate control, seven-colour ambient lighting, keyless entry and start, a sunroof, power-folding mirrors, paddle-shifters, a nine-speaker audio system with digital radio, built-in sat-nav, and a pair of 12.3 inch digital displays with wireless Apple CarPlay and Android Auto.
It also gets roof rails, side steps, privacy glass, all-terrain mode selection and a rear diff lock.
The Ultra upgrades to 18-inch wheels, Nappa leather-accented seats, heated and ventilated front seats, a heated steering wheel, more adjustment for the front seats and a memory setting, a massage function for the driver’s seat, a wireless phone charger, 64 colours in the ambient lighting suite, and a nine-speaker premium audio system.
There is nothing obvious missing from the standard features list, but I don’t know why a wireless device charger is limited to the top grade.
There are two grades in the MG S5 EV line-up. The Excite is the entry grade and the Essence is the top-of-the-range grade. Both come with a choice of two batteries - there's the smaller 49kWh battery and a bigger 62kWh battery. Now that you know this, the pricing will make more sense.
The MG S5 EV line-up starts at $40,490 with the entry grade Excite with the 49kWh battery, then steps up to $42,990 for the Essence also with the 49kWh battery. That increases to $44,990 for the Excite with the 62kWh battery and tops out at $47,990 for the Essence with this unit. All prices are drive-away.
Standard features on both the Excite and Essence include LED headlights, LED running lights and LED tail-lights, also standard are alloy wheels - 18-inch ones on the Essence and 17s on the Excite.
Both grades have proximity unlocking single-zone climate control, a 12.8 inch media display digital radio, a four-speaker stereo on the Excite and a six-speaker sound system on the Essence, while both have wireless Apple CarPlay and Android Auto, sat nav and a 10.25-inch instrument cluster.
The Essence has a few extra items the Excite doesn’t get like rear privacy glass, a panoramic glass roof, wireless phone charging, heated front seats and a power driver’s seat.
The big news with the Tank 300 is, of course, the new engine.
It is a 2.4-litre four-cylinder turbocharged diesel engine borrowed from the GWM Cannon and Cannon Alpha utes.
It pumps out 135kW of power and 480Nm of torque. That’s more torque than an MU-X but not as much as an Everest.
It is paired with a nine-speed automatic transmission and has part-time four-wheel drive.
If you need to tow, the diesel has a 3000kg towing capacity, which is 500kg more than the hybrid and petrol. It can’t beat the 3.5-tonne towing capacity of the MU-X and the Everest.
Payload has also increased compared with the petrol and hybrid, up from 400kg to 600kg.
GWM says it conducted extensive testing internationally but also in Australia to improve towing performance. There are approximately 20 different parts compared with the other powertrain variants to get the best out of towing in the diesel.
A rear diff lock is standard on both grades while the Ultra gains a front diff lock.
The MG S5 EV has one electric motor driving the rear wheels and it has an output of 125kW and 250Nm. That’s plenty of grunt to move this electric car quickly and instantly in a way that feels controllable and smooth.
While front-wheel-drive cars are absolutely fine, rear-wheel drive tends to offer more engagement and feel, and that's an added bonus for the S5 EV.
The diesel Tank 300 consumes 7.8 litres of fuel per 100 kilometres on the official combined cycle, which is better than the 9.5L figure for the petrol and the 8.4L quoted for the hybrid.
That figure also sits somewhere between a 2.0-litre bi-turbo Everest (7.1L/100km) and a 3.0L MU-X (8.3L/100km).
It has a 75-litre fuel tank and GWM claims an NEDC range of about 950 kilometres. GWM says the Euro 5 engine does not require Adblue.
Given the restrictions of a media launch, we did not obtain real-world fuel use figures.
The MG S5 EV’s energy consumption varies depending on the grade and battery size.
The most efficient in the range is the entry grade Excite with the 49kWh battery with MG saying on a combination of open and urban roads it should use 16.6kWh/100km (WLPT). The biggest energy user in the range is the Essence grade with the 62kWh battery with 17.1kWh/100km.
As for the range, this varies from 335km in the 49kWh Essence to 430km in the 62kWh Excite.
I last drove a Tank 300 in late 2023 and it was the hybrid variant. While the hybrid has some positives, its driving characteristics were not high on that list.
It had an erratic throttle response, hesitation on take-off and it felt underdone.
In contrast, this new diesel variant just feels like the right fit for this SUV.
There is slight lag accelerating from a standing start, but the powertrain is torquey and there’s plenty on tap when overtaking or just increasing speed when already on the go. GWM has not provided a 0-100km/h time.
It is clear you’re in a diesel as soon as you turn on the ignition - it has that typical diesel rattle, but it is not as unsophisticated as some oil-burners I have driven.
The cabin could do with some extra insulation with wind and tyre noise detected, but it’s hardly a deal breaker.
Given the vehicle’s size, heft (nearly 2.3-tonne kerb weight) and the fact it’s shaped like a brick, the 300 holds its nerve on winding stretches of road with only a little body roll. In saying that, best not to treat it like a Mini Cooper on your favourite twisty road.
Ride quality is a bit mixed. We only drove the Ultra on 18-inch wheels and while it manages to soak up bumps, the ride is jittery, and that’s even more evident on uneven road surfaces.
Steering is heavily weighted and a little vague, but fine for a big off-roader, and the brakes need to be pushed hard.
One quirk is the indicator - it appears to be a one-touch setup for indicating to change lanes, but then the indicator stays on. I tried several times to test this, even flicking it to the opposite side to turn it off and it was very stubborn.
The good news is it appears GWM has toned down the awful indicator sound of its earlier models and is now much more subtle.
So on-road the Tank 300 is more than competent, and a much nicer vehicle to drive in an urban setting than a Jeep Wrangler, for example.
We also drove it briefly on an off-road trail, and in low range the Tank 300 proved that it can do what it says on the box.
I’m no off-roading expert and there are much more challenging trails out there, but I had confidence that the Tank 300 would not let me down traversing the many chunky rocks, massive holes and fallen tree limbs.
The MG S5 EV is outstanding to drive for an electric vehicle at this affordable price point. Again, I’m going to put it out there and suggest it could be the new benchmark for the more affordable end of the small electric SUV segment. Kia's EV3 is also a winner on the road, but it's quite a bit pricier than the MG.
I was never a fan of the way the ZS EV drove, from its seating position to ride and handling. But the MG S5 EV is completely different to pilot. It’s excellent.
This car feels so composed on the road, the body control is excellent, the steering is well weighted and direct, the visibility is excellent and the pedal feel under my feet is solid, too. And all of that is combined with an electric motor that makes the perfect amount of power.
Add to all this the rear-wheel-drive component and the MG S5 EV is not just easy to drive but engaging as well.
ANCAP awarded the Tank 300 a five-star crash safety rating from testing done in 2022, scoring highly across all four of the major test categories.
GWM says it is waiting to hear from ANCAP but expects the diesel to be covered by the same rating.
As well as seven airbags including a front centre bag, the Tank 300 has a long list of safety gear covering both the Lux and Ultra.
There’s a suite of collision mitigation systems that includes auto emergency braking (AEB), lane departure warning, lane-keep assist, emergency lane keep, lane centring, front and rear collision warning, front and rear cross-traffic alert and lane change assist.
It also has driver fatigue monitoring, a rear seat child monitor, door opening warning, adaptive cruise, traffic sign recognition and hill-descent control.
I noted this in my recent GWM Haval H6 GT PHEV review, but GWM has made consistent tweaks to improve its advanced driver-assist systems (ADAS) and as a result they are less intrusive than they were when the Tank 300 launched in 2023.
There is still the occasional tugging of the wheel but it’s much less of a tug-of-war than it once was.
For the first 45 minutes of our test drive there was an annoying beep every 10 seconds that my co-driver and I could not identify. There was no icon on the driver display to indicate that it was a lane departure warning or speed limit alert, but eventually it just stopped. We still have no idea what it was but it was, thankfully, not present in the vehicle we drove in the second half of the launch drive.
The MG S5 EV has the maximum five-star ANCAP rating and that’s from 2025 so it is super fresh. That means it has the lot so there’s auto emergency braking (AEB), front cross-traffic alert, rear cross-traffic alert with braking, lane keeping assistance and blind spot warning, adaptive cruise control, intelligent speed limit assist and more.
There's also a driver and front passenger airbag, two side airbags, two curtain airbags and a far side airbag.
For child seats there are two ISOFIX points and three top tether anchor points.
GWM covers the Tank 300 with its seven-year/unlimited-kilometre new-vehicle warranty, which is an impressive offer.
You are covered for seven years of roadside assist and the Tank is offered with a seven-year capped-price servicing program.
GWM is yet to confirm the Tank 300 diesel’s servicing offer (including pricing), but expect a service schedule similar to the Cannon ute with the same powertrain.
That means the first service might be required at 5000km or six months and beyond that it will need a service every 12 months or 10,000km, whichever occurs first.
The MG S5 EV is covered by MG’s 10-year 250,000 kilometre warranty. And that includes the battery. Regular families though do about 10,000km a year or 20,000km maximum, so this warranty offers excellent coverage for them.
